-"""
-TODO: this will be a utility to handle secrets in the Consul database
-for the various components of the Deuxfleurs infrastructure
-
-Functionnalities:
-- check that secrets are correctly configured
-- help user fill in secrets
-- create LDAP service users and fill in corresponding secrets
-- maybe one day: manage SSL certificates and keys
-
-It uses files placed in <module_name>/secrets/* to know what secrets
-it should handle. These secret files contain directives for what to do
-about these secrets.
-
-Example directives:
-
-USER <description>
-(a secret that must be filled in by the user)
-
-USER_LONG <description>
-(the same, indicates that the secret fits on several lines)
-
-CMD <command>
-(a secret that is generated by running this command)
-
-CMD_ONCE <command>
-(same, but value is not changed when doing a regen)
-
-CONST <constant value>
-(the secret has a constant value set here)
-
-CONST_LONG
-<constant value, several lines>
-(same)
-
-SERVICE_DN <service name> <service description>
-(the LDAP DN of a service user)
-
-SERVICE_PASSWORD <service name>
-(the LDAP password for the corresponding service user)
-
-SSL_CERT <cert name> <list of domains>
-(a SSL domain for the given domains)
-
-SSL_KEY <cert name>
-(the SSL key going with corresponding certificate)
-
-RSA_PUBLIC_KEY <key name> <key description>
-(a public RSA key)
-
-RSA_PRIVATE_KEY <key name>
-(the corresponding private RSA key)
